Clayton Police / Municipal Facility historic restoration earns LEED Platinum

by Brianna Crandall — February 8, 2016—The Clayton Police Headquarters and Municipal Facility in St. Louis County, Missouri, recently received Leadership in Energy and Environmental Design (LEED) Platinum green building certification from the U.S. Green Building Council (USGBC), earning 80 out of a possible 110 points.

The historic restoration project was a joint venture for Western Specialty Contractors’ St. Louis Masonry Branch and St. Louis Concrete Branch, which are said to be earning praise for their role in the restoration. St. Louis Masonry was contracted to restore the building’s exterior, and St. Louis Concrete to restore the building’s attached, 168-space parking garage.

The architect for the project was Lawrence Group, the engineer was KPFF Engineers, and the construction manager was Paric, all of St. Louis, Missouri.

The Clayton Police Headquarters and Municipal Facility occupies 22,000 square feet of a historic, six-story structure in Downtown Clayton at 10 S. Brentwood Ave. The primary goal of the restoration project was to maintain the building’s historic character while incorporating modern, sustainable technology and design.

Green features of the project include on-site energy generation using the largest, single-site solar array in the state of Missouri; high-efficiency HVAC, lighting and water systems; a refurbished and improved exterior envelope; and a commitment throughout the facility to indoor air quality (IAQ) and environmental controls for all building occupants.

The scope of work for Western’s St. Louis Masonry branch (building’s exterior) comprised:

  • Tuckpointing
  • Brick replacement
  • Caulking of settlement cracks
  • Removal of efflorescence and stains

The scope of work for Western’s St. Louis Concrete branch (attached, three-level parking garage) encompassed:

  • Partial-depth and full-depth concrete slab repairs
  • Vertical and overhead ceiling concrete repairs
  • Post-tensioning tendon repairs
  • Installation of a urethane traffic coating

Maintaining proper dust control during both projects was reportedly a major challenge for Western and extremely important to preserving the function of the solar panels, located on the roof of the parking garage. Western’s solution was to use shop vacuums while cutting out the mortar, and a combination of swing stages, pipe scaffolding and aerial lifts for efficiency.
